Purpose To grade myopic choroidal neovascularization (CNV) patients according to the new myopic maculopathy classification (A: atrophy, T: traction, N: neovascularization-ATN) and analyze the correlation in between atrophy, traction and neovascularization. Methods Fifty-one eyes of 41 patients with the diagnosis of pathologic myopia and myopic CNV were included in this clinical practice study. Patients were graded according to the recently described ATN classification. Color fundus photographs were used to grade the atrophy and spectral domain optical coherence tomography scans were used to grade traction and neovascularization. Active myopic CNVs were treated with intravitreal anti-vascular endothelial growth factor (VEGF) injections. Chi-square test was used to test the categorical variants and univariate logistic regression analysis was used to predict the independent risk factors of myopic CNV scar formation. Results Active myopic CNV was observed most frequently in the group with patchy chorioretinal atrophy. Grade of the atrophy and female gender were significantly associated with myopic CNV scar in the univariate logistic regression tests. Multivariate logistic regression showed that atrophy grading is the independent predictor of myopic CNV scar. Conclusion ATN classification is a practical and comprehensive system to grade myopic CNV. Atrophy is an independent predictor for myopic CNV scar and patchy chorioretinal atrophy requires a more careful examination and close follow-up for the risk of CNV development.

Purpose. Since quantification and communication of ocular pain is important for a healthier patient follow-up and postoperative guidance, reliable measures like the Ophthalmic Pain Assessment Survey (OPAS) are needed to assess the outcome and management of different operations. To address that need, we carried out the adaptation of OPAS into Turkish to reach different age groups and backgrounds, widening the use of OPAS on patients who underwent an ophthalmic operation. Methods. We used back-translation method and achieved cultural adaptation through content validity scoring by 5 independent ophthalmologists. The survey is then administered three times: preoperatively, postoperatively within 24 hours, and finally a week later in the follow-up visit. Validity is measured in comparison to Visual Analog Scale using Spearman's correlation coefficient and reliability is measured using Cronbach's alpha. Factor analysis is performed by principal component analysis and rotation is performed using Varimax method when necessary. Results. We reached a total of 132 patients with a mean age of 64.2 years. Most of them underwent phacoemulsification (n = 83), followed by PRK (n = 37). Overall, the T-OPAS demonstrated good reliability (mean C. alpha: 0.830) and its correlation with the VAS was especially high (S. coeff. >0.5) in the first three sections in all three surveys. Factor analysis yielded 5 subscales, allowing us to shape the final form of T-OPAS. Conclusion. Through this adaptation of OPAS into a foreign language, we present a reliable and valid tool for postoperative pain quantification, allowing objective measurement of pain in different populations such as the elderly.
Heavy Silicone Oil as an Endotamponade in Recurrent or Complicated Retinal Detachment and Macular Hole
(2022) Kurt, Rengin Aslihan; Kapran, Ziya; 35481733
Objectives: To evaluate the efficacy and safety of heavy silicone oil as an endotamponade in patients with recurrent or complicated retinal detachment and macular hole. Materials and Methods: Nineteen eyes of 19 patients who underwent heavy silicone oil endotamponade for different indications were included in the study and evaluated by retrospective chart review. At each visit, patients underwent detailed ophthalmological examination and anatomical and functional outcomes, silicone oil emulsification, intraocular inflammation, presence of proliferative vitreoretinopathy, preoperative and postoperative visual acuity, and postoperative complications were recorded. Results: The study included 19 eyes of 19 consecutive patients: 13 women (68.4%) and 6 men (31.6%). The patients' median age was 60 years (interquartile range [IQR]: 44-70 years) and the median follow-up time was 19 months (IQR: 9-31 months). Indications for heavy silicone oil endotamponade were recurrent retinal detachment in 11 eyes (57.8%), inferior retinal detachment in 5 eyes (26.3%), inferior rhegmatogenous retinal detachment, recurrent macular hole in 2 patients (10.5%), and macular hole in 1 patient (5.2%). Median best corrected visual acuity was 2 logMAR (IQR: 1-2.6) preoperatively and 0.99 logMAR (IQR: 0.4-2) postoperatively (p<0.001). Postoperative anatomical success was achieved in all patients. Densiron 68 was used for endotamponade in 14 patients (73.7%), Densiron XTRA in 3 patients (15.8%), and AlaHeavy 1.07 in 2 patients. Heavy silicone oil emulsification was observed in only 3 patients (15.8%). Conclusion: Although heavy silicone oil has limitations as an endotamponade, such as intraocular pressure increase, emulsification, intraocular inflammation, and the risk of complications during removal, it is a safe and effective alternative in eyes requiring inferior retinal tamponade for indications like proliferative vitreoretinopathy and recurrent macular holes
