“…In our study population, the rate of cataract extraction was significantly higher after PPV than after SB and PR. Other comparative studies have found similar results 43 , 55 and data in the literature generally point to a small risk of cataracts after SB 56 and PR. 35 , 38 , 57 , 58 A statistically significant difference in the rate of cataract extraction was detected between PPV with and without SB in this study and is in agreement with observations by Kinori et al 46 Therefore, although SB by itself carries a low risk of cataracts, the risk increases significantly when SB is combined with PPV.…”

PurposeTo evaluate the incidence and prevalence of cataract formation, progression, and extraction in patients that underwent vitreoretinal procedures and to evaluate factors that can potentially predispose patients to postoperative cataracts.Materials and methodsThe medical records of consecutive patients who underwent vitreoretinal surgery at the Yale Eye Center with at least 6 months of follow-up and no prior intraocular surgery were obtained. Preoperative, intraoperative, and postoperative data were recorded and analyzed in this retrospective observational study. The main outcome measures were defined as cataract extraction, formation, and progression after vitreoretinal procedures. The lens status of the surgical eye was recorded preoperatively and at 1 month, 3 months, 6 months, 12 months, 24 months, and 36 months postoperatively.ResultsA total of 193 eyes of 180 patients fulfilled the inclusion criteria. The percentages of eyes with mild lens change were 96% after 20-gauge pars plana vitrectomy (PPV), 72% after small gauge (23- and 25-gauge) PPV, 38% after scleral buckle (SB), 38% after pneumatic retinopexy (PR), and 91% after PPV plus SB (PPV+SB). Posterior subcapsular and nuclear sclerotic cataracts were the most common with almost all developing within 24 months. There was no statistically significant difference (P=1.00) between the rate of cataract extraction after 20-gauge (41%) and small gauge PPV (42%), but there was a statistically significant difference between PPV and non-PPV (SB, 6%; PR, 7%; P<0.001) and PPV and PPV+SB groups (69%; P=0.0063).ConclusionCataracts were common following PPV regardless of the gauge. SB and PR led to the lowest while PPV+SB led to the highest risk of postoperative cataracts.

“…The feel ing of better postoperative vision increased for 1-2 years after operation, decreased for 2-3 years, was stationary for 5-10 years and then decreased again after 10 years. The change in this postoperative satisfaction with vision correlated well with the actual prognosis of visual acuity after surgery for detached retina [Amemiya et al, 1978, Blurred vision was complained of by 30.5% and metamorphopsia by 31.1% (table III). These two were the most frequent com plaints in all groups regardless of the post operative interval.…”

A questionnaire about postoperative complaints was given to patients after surgery for retinal detachment. Their visual acuity and visual field problems were analyzed. Only one third of all the patients felt postoperative improvement. Blurred vision and metamorphopsia after operation were complained of in one third of all the patients. Blurred vision was apt to be complained of in patients with macular detachment before operation. About 77% of patients with blurred vision had a visual acuity of less than 0.5. Metamorphopsia was frequently complained of in patients treated with the segmental buckling procedure.

“…The precise effect of RD on the renewal of ROS is unclear. The ROS is observed to degenerate when the retina detaches [19, 20], and photoreceptor cells in a detached retina die after a certain time [16, 17, 21–23]. Thus, the mechanism responsible for the degeneration of ROS during RD, and those that dictate the survival time of rod cells in a detached retina are unknown.…”

“…It is however well established that shedding, as understood by the engulfment of discs by the RPE, stops during RD due to the separation of the NL from the RPE [19, 20]. The photoreceptor cells in a detached retina die after a certain period [16, 17, 21–23], however, if RD is treated on time, and the retina is reattached to the RPE, the possibility of rod and cone cell regeneration, and hence restoration of vision is high. Currently, the time frame within which retinal reattachment must be performed to restore vision is unknown [23].…”

Mathematical model for rod outer segment dynamics during retinal detachment and reattachment

Retinal detachment (RD) is the separation of the neural layer from the retinal pigmented epithelium thereby preventing the supply of nutrients to the cells within the neural layer of the retina. In vertebrates, primary photoreceptor cells consisting of rods and cones undergo daily renewal of their outer segment through the addition of disc-like structures and shedding of these discs at their distal end. When the retina detaches, the outer segment of these cells begins to degenerate and, if surgical procedures for reattachment are not done promptly, the cells can die and lead to blindness. The precise effect of RD on the renewal process is not well understood. Additionally, a time frame within which reattachment of the retina can restore proper photoreceptor cell function is not known. Focusing on rod cells, we propose a mathematical model to clarify the influence of retinal detachment on the renewal process. Our model simulation and analysis suggest that RD stops or significantly reduces the formation of new discs and that an alternative removal mechanism is needed to explain the observed degeneration during RD. Sensitivity analysis of our model parameters points to the disc removal rate as the key regulator of the critical time within which retinal reattachment can restore proper photoreceptor cell function.
