Hereditary Retinal Disease

Hereditary retinal disease (HRD) is a group of pathologies characterized by histologically abnormally developing vitreous gel associated with peripheral retinal degenerative or proliferative changes. In HRD alterations in the structure of the vitreous with abnormal vitreoretinal adhesions can predispose to developing Retinal Detachment (RD). Many HRD is seen with a part of syndromes most of which have systemic abnormalities affecting the joints, skeletal system, and cardiovascular system.  Due to delayed diagnosis in younger age patients,  without prominent symptoms, most patients with HR presented with proliferative vitreoretinopathy PVR and macula-involving RD.

BACKGROUND: Despite significant advances in the technology of surgical treatment of regmatogenous retinal detachment, a certain proportion of patients with emerging macular edema against the background of silicone oil tamponade remains. AIM: To evaluate the risk factors of macular edema development and to work out a mathematical model for its prediction based on a retrospective analysis of clinical data of patients with rhegmatogenous retinal detachment complicated by proliferative vitreoretinopathy. MATERIALS AND METHODS: A retrospective case series of 64 patients (64 eyes) with regmatogenous retinal detachment complicated by grade CP proliferative vitreoretinopathy who underwent primary retinal detachment repair. Patients were divided into two groups: with the presence of macular edema in the postoperative period and without it (32 patients in each group). In all cases, at the initial examination, retinal detachment involved the macular area. RESULTS: Using regression analysis, two significant factors were identified: the sum of the 8 meridians of the visual field before surgery (p=0.015) and the number of detached quadrants (p=0.021). Based on the identified factors, a model for predicting macular edema occurrence in the postoperative period in the surgical treatment of regmatogenous retinal detachment was obtained. CONCLUSIONS: The investigation results allowed establishing that the retinal detachment area and the sum of the 8 meridians of the visual field are significant pre-operative factors for macular edema development in retinal detachments with proliferative vitreoretinopathy of CP 1-2 degree. The developed mathematical model based on these indicators is characterized by significant information content and allows predicting macular edema occurrence in the postoperative period. The use of the proposed prognostic model determines a differentiated approach to surgical prevention of macular edema and allows making a decision on the removal of internal limiting membrane at the preoperative stage.

Purpose: To investigate the risk factors for the development of proliferative vitreoretinopathy grade C (PVR-C), independent of prior surgical invasion. Methods: Patients who underwent surgery for rhegmatogenous retinal detachment were prospectively registered with the Japan-Retinal Detachment Registry, organized by the Japanese Retina and Vitreous Society, between February 2016 and March 2017. Data obtained from general ophthalmic examinations performed before and at 1, 3, and 6 months after surgery were analyzed. Results: We included 2013 eyes of 2013 patients (men, 1326 (65.9%); mean age, 55.2 ± 15.2 years) from amongst 3446 registered patients. Preoperative PVR-C was observed in 3.6% of patients. Propensity score matching revealed that a shorter axial length (AL) was a risk factor for preoperative PVR-C (OR (Odds Ratio), 0.81; 95%CI (Confidence Interval), 0.69 to 0.96; p = 0.015), which was a risk factor for surgical failure (OR, 4.22; 95%CI, 1.12 to 15.93; p = 0.034); the association was particularly significant for eyes with an AL < 25.0 mm (p = 0.016), while it was insignificant for eyes with an AL ≥ 25.0 mm. Conclusions: A shorter AL was related to the development of PVR-C before surgical invasion. Our results will help elucidate the fundamental pathogenesis of PVR and caution clinicians to meticulously examine eyes with a shorter AL to detect retinal detachment before PVR development.

Purpose: To evaluate the risks that might be associated with recurrent macular hole retinal detachment (Re MHRD) after silicone oil (S.O) removal in myopic patients with open flat macular hole (MH). Methods: In this retrospective series, we assessed the different factors that might be associated with recurrent MHRD after S.O removal in 48 eyes with open flat MH that underwent S.O removal after successful MHRD repair by dividing the enrolled eyes into 2 groups: group 1 included 38 eyes with flat open MH and flat retina after S.O removal and group 2 included 10 eyes with flat open MH and recurrent MHRD after S.O removal. Results: Ten of 48 eyes (20.8%) with open flat MH developed recurrent MHRD after S.O removal. Univariate logistic regression analysis revealed that MH at the apex of PS, MH minimum diameter, hole form factor (HFF) and MH index (MHI) were significant risk factors for recurrent MHRD after S.O removal in myopic patients with open flat MH. Conclusions: If there is a "flat open" MH that is large, located at the apex of PS or with HHF or MHI of less than 0.9-0.5, it has a high chance of recurrent MHRD after S.O removal.
