“…Most studies have reported that the final postoperative vision of patients is closely related to the structure of the macular area 11‐13 . In this study, it was also found that the visual acuity of patients with relatively healthy macular before surgery was significantly improved, while the improvement in visual acuity of patients with significantly thinner macular was limited.…”

Effect of lens capsular tension ring on preventing capsular contraction syndrome in the surgery of retinitis pigmentosa combined with cataract: Retrospective case series

Retinitis pigmentosa (RP) is a clinically common congenital retinal disease, with an incidence of about 1/4000. 1 The pathological manifestations include progressive dysfunction of retinal pigment epithelial cell and photoreceptor cell, and patients tend to be night blind and have reduced vision field and poor vision. Currently, there is no effective treatment or prevention measures for RP, and interventions such as stem cell transplantation and gene therapy are still in the research stage. 2,3 In addition to primary retinal damage, RP is usually accompanied by other eye diseases. Cataract is one of the most common complications of RP. 4 Patients with RP complicated with cataract are young in age and progress rapidly, which has a great impact on the remaining vision of patients, and usually, patients would need surgical treatment. This paper retrospectively analysed the vision, intraocular pressure (IOP), corneal endothelial cell count (ECC), macular morphology and postoperative complications of 63 patients (84 eyes) who underwent phacoemulsification

“…They have been used extensively in the west to prognosticate visual outcomes after surgery. [ 15 23 24 25 ] In our study, we identified reduced central macular thickness in OCT as a risk factor for poor visual outcomes. Macular thinning indicates deteriorating photoreceptor activity and central retinal function.…”

“…[ 21 ] We did not routinely perform these tests in the preoperative workup, because all these tests have high variability and poor reliability in the presence of dense cataract. [ 25 ] They also increase the costs, a constraint in developing economies. We identified preoperative visual acuity to be an important prognostic factor.…”

Purpose: The aim of this study was to evaluate visual outcomes of cataract surgery in patients with retinitis pigmentosa. Methods: This retrospective case series includes a review of the medical records of all patients with retinitis pigmentosa undergoing cataract surgery between 2005 and 2018. The primary outcome measure was corrected distant visual acuity and change in vision impairment after surgery. Results: Of the 103 (132) patients, 60 (58.3%) were men and 43 (41.7%) were women. The mean age of the study population was 51.3 ± 11.3 (22–74) years. The mean symptom duration was 35.4 ± 44.5 (1–300) months. The most common morphology of cataracts was a combination of nuclear sclerosis, posterior subcapsular, and cortical cataract ( n = 65 eyes, 49.3%). Phacoemulsification (87 eyes, 65.9%) was the preferred surgical technique. The mean preoperative corrected distant visual acuity of 1.21 ± 0.87 log MAR units improved significantly ( P < 0.001) to 0.60 ± 0.56 log MAR units after surgery. The number of blind patients reduced from 27 (26.2%) to 8 (7.8%) patients. Zonular dialysis and posterior capsule tear were seen in six (4.5%) eyes each. Good preoperative vision (odds ratio: 6.1 [95% confidence interval: 2.9–13.0], P < 0.0001) was associated with better outcome, wheras reduced central macular thickness (odds ratio: 3.5 [95% confidence interval: 1.3–9.2], P = 0.011) was associated with poor outcome. Conclusion: A considerable number of patients presented with advanced cataracts and severe vision impairment. Significant improvement in visual acuity and alleviation of vision impairment was seen after surgery, with few complications. Good preoperative visual acuity predicted a good outcome, whereas macular thinning predicted a poor outcome.

“…However, the RNFL thickness was found to be retained or thickened in the majority of RP patients, and the measurement results are shown in table 2[44,53,54,55,56,57,58]. In addition to the mean RNFL changes [44,55], the quadrants of the RNFL thickening or thinning were different.…”

Retinitis pigmentosa (RP) is a progressive inherited retinal disease characterized by nyctalopia, visual field constriction, and reduced full-field electroretinograms. The progressive loss of photoreceptors leads to vision loss at the end stage of RP. The prevalence of RP is approximately 1/4,000. Since it is one of the major causes of visual impairment worldwide, morphological and functional assessments are useful for estimating the retinal structure and function in RP. Optical coherence tomography (OCT) is a well-established method of examining retinal structure in situ, and the obtained images by OCT help to analyze morphological abnormalities. Changes revealed by OCT have provided insights into the pathology of RP as well as for predicting the prognosis of RP. In this review, we present the typical morphological changes in RP and their relationships with visual function in eyes with RP.
