        Long-term Effects of Uncomplicated Traumatic Hyphema on Corneal and Lenticular Clarity

        Ali Keles(Ali Keles ),Pinar Kosekahya(Pinar Kosekahya ),Furkan Emre Sogut(Furkan Emre Sogut ),Mustafa Salih Karatepe(Mustafa Salih Karatepe ) 대한안과학회 2022 Korean Journal of Ophthalmology Vol.36 No.6

        Purpose: To evaluate the long-term effects of uncomplicated traumatic hyphema on endothelial morphology, anterior segment structure, and corneal and lenticular densitometry Methods: In this retrospective comparative study, eyes with a history of uncomplicated traumatic hyphema were compared with the healthy contralateral unaffected eyes. The corneal endothelial cell properties were captured using specular microscopy. Anterior segment analysis, corneal densitometry (12-mm corneal diameter), and lens densitometry measurements were performed using the Pentacam imaging system. Results: Measurements were obtained at a mean follow-up of 49.5 ± 15.8 months after injury. The average endothelial cell density was significantly lower in the study group than in the control group (2,506.6 ± 294.0 cells/mm² vs. 2,665.7 ± 195.0 cells/mm², p = 0.020). There was no difference between the groups in respect of polymegathism and pleomorphism (p = 0.061 and p = 0.558, respectively). All the investigated corneal tomographic and angle parameters were similar in both groups (all p > 0.05). The corneal densitometry values in all concentric zones and layers showed no statistically significant difference between the groups (p > 0.05 for all). The lens zone 1 densitometry value was significantly higher in the study group than in the control group (9.6% ± 1.1% vs. 8.9% ± 1.2%, p = 0.031). No difference was observed in zone 2 and 3 (p = 0.170 and p = 0.322, respectively). The degree of hyphema was not correlated with endothelial cell and lenticular clarity loss (p = 0.087 and p = 0.294, respectively). Conclusions: Even if traumatic hyphema is not complicated, long-term outcomes indicate endothelial cell loss and increased lenticular density.

        Evaluation of Genetic Analysis with Autosomal Recessive Bestrophinopathy

        Ali Mert Kocer,Mehmet Yasin Teke,Furkan Emre Sogut 한국망막학회 2019 Journal of Retina Vol.4 No.2

        Purpose: We aimed to report a patient with autosomal recessive bestrophinopathy (ARB) who have novel compound heterozygous mutations in BEST1. Case summary: A 35-year old male patient who had no history of known trauma and disease was admitted to our hospital with bilateral visual disturbance since his childhood. Dilated fundus examination revealed widespread yellow-white subretinal accumulation and white scar formation on both posterior poles. Hyperfluorescent foci were observed along the vessel arcades in fundus autofluorescence imaging. Optical coherence tomography showed serous subretinal fluid under the bilateral macula. Arden rate was found to be 1.32 for right eye and 1.28 for left eye in the electrooculography examination. Bestrophinopathy was considered in the patient and a genetic examination test was performed for BEST1 gene. The whole gene sequence analysis test (Miseq-Illumina) performed on the BEST1 gene of the patient resulted in c.604C>T (p.Arg202Trp) (pR202W) /c.1013G>A (p.Trp338 *) (p.W338*) compound heterozygous mutation. Conclusions: ARB is a rare disease and usually associated with consanguineous marriage, the disease may also occur with different mutations of both spouses. For this reason, it is important that ophthalmologists consider the possibility of best retinopathy even in the absence of a consanguineous history.
