Purpose: Preferential hyperacuity perimeter (PHP) is a device that measures metamorphopsia in the central 14° of the macular visual field which is presented by hyperacuity defect. We elucidated a hyperacuity defect lesion of PHP in exudative age-related macular degeneration (AMD) by Optical coherence tomography (OCT). Methods: Nineteen eyes of 18 patients with exudative AMD diagnosed by fundus examination and fluorescein angiography (FA) underwent PHP. We then elucidated any hyperacuity defect lesion of PHP by fundus photography, FA and OCT. For a control, 20 eyes of 10 age-matched persons who had no ophthalmological abnormality underwent PHP and OCT to determine if hyperacuity defect would appear. Results: Hyperacuity defect lesion appeared in 18 eyes (95%) of AMD patients. There was good locational correlation between the hyperacuity defect lesions and lesions in the fudoscopic examination in 16 eyes of 18, but there was a counterpart relation at the superior-inferior and left-right in 2 eyes. Hyperacuity defect lesion in PHP was of smooth or irregular elevation of the retinal pigment epithelium (RPE) in OCT. In the control, hyperacuity defect lesion appeared in 1 eye (5%) and it was normal in OCT. Conclusions: PHP showed a highly positive rate in detecting AMD-related lesion. The hyperacuity defects that are noted by the PHP are produced from elevation of the RPE.

Purpose: The Preferential Hyperacuity Perimeter (PHP) is a device designed to monitor the development of choroidal neovascularization in age-related macular degeneration (AMD) patients. Recent studies have reported the efficacy of the PHP in early detection of AMD. To evaluate hyperacuity, a dot deviation signal is flashed to the central 14 degrees of the macular visual field and the patient`s perceived hyperacuity defect is recorded. The purpose of our study was to identify the role of the PHP in analyzing visual functions of patients with maculopathy caused by retinal diseases other than AMD. Methods: Seventy-four eyes of 55 patients with macular abnormalities caused by various retinal diseases (44 eyes of diabetic retinopathy, 6 eyes of central serous chorioretinopathy, 24 eyes of other retinal diseases) underwent PHP, Optical Coherence Tomography (OCT) and fluorescein angiography (FAG). Results: Of the 74 eyes with maculopathy, 60 eyes (81%) were positive on the PHP. By disease, 40 eyes (40/44, 91%) with diabetic retinopathy, 3 eyes (3/6, 50%) with central serous chorioretinopathy and 17 eyes (17/24, 71%) with other retinal diseases were positive. Among them, the location of hyperacuity defect lesions determined by PHP correlated well with the location shown on OCT and FAG in 6 eyes (6/40, 15%) with diabetic retinopathy, 1 eye (1/3, 33%) with central serous chorioretinopathy and 5 eyes (5/17, 29%) with other retinal diseases. Conclusions: Many retinal diseases that lead to maculopathy revealed a hyperacuity defect on PHP when the lesion was located not only in the retinal pigment epithelium but also in the outer retinal layer. Special attention to the patient`s visual acuity and visual field defects is required when analyzing PHP results since these factors can influence the PHP evaluation.

Purpose: To analyze the optical coherence tomography (OCT) result at the area of hyperfluorescence by scanning laser ophthalmoscopy (SLO) in central serous chorioretinopathy. Methods: We investigated sensory detachment, pigment epithelial detachment (PED), choroidal neovascularization (CNV), and retinal pigment epithelial atrophy using OCT in the area of hyperfluorescein by scanning laser ophthalmoscopy (SLO) in 29 eyes of 29 patients with CSC. Results: Of 29 eyes, no specific finding was noted in 19 eyes. Small PED corresponding to the leaking point was noted in 3 eyes, large serous PED with leaking point in 2 eyes, hemorrhagic PED in 1 eye, subretinal precipitate and PED in 1 eye, and retinal pigment epithelial atrophy in 2 eyes. Conclusions: OCT provided intuitive and objective information on the pathophysiologic state of the retinal pigment epithelial layer at the area of hyperfluorescence by SLO in CSC.

Purpose: To report a case of retained Descemet’s membrane after penetrating keratoplasty (PKP). Case summary: A 64-year-old man visited our clinic, complaining of visual disturbance and corneal opacity in his right eye 40 years in duration. On the first visit, his best corrected visual acuity was hand movement on the right eye, and he underwent an uneventful PKP. On the postoperative first day, the patient’s visual acuity was 20/200 and slit lamp examination showed a retained Descemet’s membrane and pseudo-chamber behind the corneal graft. The corneal graft was edematous, but no intraocular inflammation was observed. The retained Descemet’s membrane was surgically removed a quarter at a time. Sutures in one quadrant were removed; the retained Descemet’s membrane was lifted with forceps, removed with scissors and knife, and then sutured again. Two months after PKP, the corneal graft remained clear and no intraocular inflammation was observed. An extracapsular cataract extraction (ECCE) was then successfully performed with posterior chamber lens implantation for the senile cataract in his right eye. After the 1-year follow-up, the status of the corneal graft remained clear with a single anterior chamber and best corrected visual acuity improved to 20/100. Conclusions: Careful post-operative slit-lamp examination is considered important for diagnosis of retained Descemet’s membrane after undergoing PKP, and surgical removal can be helpful for maintaining the corneal graft clear.

Purpose: To compare the choroidal thickness in central serous chorioretiopathy (CSC) patients and normal controls using spectral domain optical coherence tomography (SD-OCT). Methods: The authors compared the choroidal thickness in eyes with CSC, fellow eyes and in normal eyes. In addition, the authors attempted to determine any correlation between choroidal thickness and other factors such as age, height of serous retinal detachment, and spherical equivalent. Choroidal thickness was measured using a perpendicular line from the outer margin of the subfoveal retinal pigment epithelium to the inner surface of the sclera. Results: Twenty-five eyes of 25 CSC patients, 17 fellow eyes and 29 age-matched normal eyes were examined and categorized as group 1, group 2 and group 3, respectively. Subfoveal choroidal thickness was 370.64 ± 58.06 μm in group 1, 301.85 ± 47.83 μm in group 2, and 261.84 ± 48.22 μm in group 3. The choroidal thickness in group 1 was significantly greater than those in group 2 and group 3, and the choroidal thickness in group 2 was significantly greater than that in group 3 (p = 0.001, p < 0.001, p = 0.004, respectively), where the choroidal thickness showed a negative correlation with age (p = 0.015). Conclusions: The choroidal thickness was greater in eyes with CSC and in their fellow eyes compared to that in normal eyes. The results suggest that CSC may be caused by choroidal vascular hyperpermeability and increased hydrostatic pressure in the choroid. J Korean Ophthalmol Soc 2012;53(1):87-93

Purpose: To report the use of autologous Tenon’s capsule graft for repair of scleral defects caused by traumatic scleral perforation. Case summary: An 81-year-old man presented with loss of vision in his right eye after a perforating injury caused by a cow horn. Examination showed a laceration of the sclera at 12 o’clock approximately 5~6 mm in length, and a uveal tissue was prolapsed into the wound. The best corrected visual acuity was 0.1. Primary repair of the eye was insufficient because of tissue loss. The inferonasal Tenon’s capsule graft was carefully dissected from the sclera and tailored to fit the defect. The graft was covered with a conjunctival flap. The scleral defect was successfully closed with the autologous Tenon’s capsule graft. Three months after grafting, phacoemulsification with intraocular lens implantation was performed. Conclusions: Autologous Tenon’s capsule graft is an effective measure to repair traumatic scleral defects and is useful when patch grafts are unexpectedly needed.

Purpose: To assess the clinical course of submacular hemorrhage (SMH) due to various chorioretinal diseases with or without pneumatic displacement and the factors related with the final visual outcome. Methods: The authors of the present study retrospectively reviewed the charts of 12 eyes (group 1) which underwent pneumatic displacement for SMH and the charts of 14 eyes (group 2) which did not receive pneumatic displacement. Best-corrected visual acuity (BCVA) at baseline was compared with the BCVA at 1, 3, and 6 months and on the final visit. Association between final BCVA and other clinical features was analyzed including age, baseline BCVA, duration of symptoms, and size of SMH. Results: In group 1, log MAR BCVA was 1.22 ± 0.66 at baseline and there was a significant BCVA improvement of 0.77 ± 0.57 at 6 months compared with baseline (p = 0.045). On the final visit, 6 eyes (50%) had gained 2 Snellen lines or more. In group 2, BCVA was significantly improved from 1.29 ± 0.70 at baseline to 1.06 ± 0.84 at 1 month (p = 0.045). Ten eyes (71.4%) had gained 2 Snellen lines or more on the final visit. In group 1, there were no factors correlated with final BCVA (p > 0.05), while the final BCVA was significantly correlated with age and baseline BCVA in group 2. Conclusions: Clinicians may expect conservative treatment to lead to significant improvement of BCVA in patients with SMH due to various chorioretinal diseases who did not undergo any procedures to displace the hemorrhage.

Purpose: To analyze the long-term results of photodynamic therapy (PDT) for exudative age-related macular degeneration (AMD). Methods: The clinical data of patients treated with photodynamic therapy for exudative age-related macular degeneration between April 2000 and December 2000 were analyzed. Patients were followed-up for at least 10 years after PDT. Results: Twenty-nine eyes of 29 patients were enrolled. Mean visual acuity on the logarithm of the minimum angle of resolution (log MAR) scale was 0.78 ± 0.34 at baseline, 1.01 ± 0.42 at 60 months, and 1.02 ± 0.41 at 120 months. Predominantly classic, minimally classic, and occult without classic choroidal neovascularization was noted in 51.7%, 17.2%, and 31.1% of patients, respectively. Visual acuity was improved by 1 or more lines in 27.6% of patients and was unchanged in 20.7% of patients, while 51.7% of patients had lost 1 or more lines of visual acuity by 120 months. Baseline visual acuity and age were associated with the final visual prognosis (p < 0.05). Four patients developed neovascular AMD in the contralateral eye. Conclusions: PDT is safe and effective for neovascular AMD. However, AMD can recur at any time and thus patients should be followed-up for a long period of time.
