From May 2017 to March 2020, 62 MHRD patients with PS(62 eyes) were enrolled in the study. Patients were divided into 23 G PPV combined with PS marginal retina intraoperative photocoagulation group(combined group) and conventional surgery group(conventional group), with 31 eyes in each. Triamcinolone acetonide and indocyanine green were used to remove the epiretinal membrane and the posterior macular inner limiting membrane(ILM). In the combined group, 2 to 3 rows of retinal photocoagulation were performed on the edge of the PS. The patients were followed up for an average of 8.34±3.21 mo. The first retinal reattachment rate, macular hole closure rate, Duration of silicone oil tamponade, best corrected visual acuity(BCVA) and average number of operations were observed and compared between the two groups.RESULTS: The first retinal reattachment rates of the eyes in the combined group and the conventional group were 96.7%(29/31) and 67.7%(21/31), respectively(χ~2=6.613, P=0.010). The macular hole closure rates in the combined group and the conventional group were 74.2%(23/31) and 67.7%(21/31), respectively(χ~2=0.128, P=0.721). The Duration of silicone oil tamponade of the patients in the combined group was lower than that of the routine group(t=-41.962, P≤0.001). Postoperative log MAR BCVA values of patients in the combined group and the conventional group were 1.27±0.12 and 1.26±0.11, compared with the log MAR BCVA before surgery, each group was improved(t=19.947, t=-19.517, P≤0.001, P≤0.001). There was no significant difference in the log MAR BCVA between the eyes of the two groups(t=-0.394, P=0.695). The average numbers of operations on the eyes in the conventional group and the combined group were 2.39±0.62 and 2.06±0.25 times, the combined group had fewer operations on average(t=-2.705, P=0.009). CONCLUSION: Intraoperative PPV treatment of MHRD with PS combined with PS marginal endolaser photocoagulation can effectively increase the rate of retinal reattachment after the first operation, reduce the number of repeated operations, and reduce the postoperative duration of silicone oil tamponade.展开更多

There was history of pain and redness of the eyes associated with discharge. She was not vaccinated at all. She was chronically ill-looking with bilateral conjunctival hyperaemia, purulent eye discharge with corneal opacity of the right eye. She had significant lymphadenopathy, digital clubbing and ulcerated, discharging swellings around her neck and axilla (scrofuloderma). She had reduced breath sounds and coarse crepitations. Hepatosplenomegaly and ascites were present. She later developed bulging of the upper part of the cornea of the right eye which was diagnosed by the ophthalmologist to be cornea ulcer with anterior staphyloma. <b>Results, Treatment and Outcome</b>: Complete blood count (leucocytosis 12,800 cells), erythrocyte sedimentation rate (150 mm/hr) and tuberculin test (7 mm induration) were suggestive of TB. Radiological tests were also supportive. She received anti-Kochs in addition to systemic and ocular antibiotics. Skin lesions healed progressively and stopped discharging. Caregivers were counseled on poor visual prognosis of the right eye. She was discharged but lost to follow up. <b>Conclusion</b>: Multi-organ involvement of TB especially ocular and cutaneous TB is not common but is very debilitating. More preventive efforts with vaccination and expertise are needed at lower levels of health care in the community to aid early diagnosis.展开更多

The first patient was a 3-year-old young girl underwent corneal dermoid resection. The second patient was a 60-year-old man underwent nasal pterygium excision and conjunctival autograft without Mitomycin C(MMC). The other two were respectively a 74-year-old woman and a 69-year-old man underwent cataract surgery. All patients performed allogeneic sclera patch graft. In the at least half a year follow-up, the best corrected visual acuity(BCVA) of all the four patients were no worse than that of preoperative. Ocular symptoms disappeared, including eye pain, foreign body sensation, and so on. Unfortunately, the fourth patient showed sclera rejection and partial dissolution at postoperative 1 month. Conclusions: Surgically induced scleral staphyloma must be considered in the differential diagnosis of patients with staphyloma following corneal dermoid, pterygium, and cataract surgery. Allogeneic sclera patch graft is one of the methods for treating scleral staphyloma. However sclera rejection and dissolution should be considered postoperatively.展开更多

Aim: To describe the microstructural and functional results in three highly myopic eyes that underwent macular surgery for early-stage MTM. The last postoperative structural findings were correlated with the final vision and macular automated microperimetry evaluation. Methods: We retrospectively reviewed three highly myopic eyes that underwent successful fovea-saving internal limiting membrane (FS-ILM) macular surgery for chronic FRD at Oftalmologia Integral ABC, Mexico City, Mexico. We performed postoperative multimodal microstructural and functional evaluations, including SD-OCT, SS-OCT, and microperimetric macular examinations. Results: There was a substantial difference between best-corrected visual acuity (BCVA) preoperatively and postoperatively in all three cases. Postoperative surgery was associated with significant improvement in visual acuity confirmed using a paired-sample permutation test. The mean presurgical BCVA value (LogMAR;mean ± SE) was ~0.83 ± 0.15, and the postsurgical value was ~0.43 ± 0.52 (P = 0.00065). The myopic foveoretinal detachment evaluation was ~7.3 ± 3.5 months, with a mean postoperative follow-up time of ~14 ± 4.08 months. Furthermore, postoperative multimodal imaging tests demonstrated an abnormal microstructural foveal SS-OCT pattern without evidence of macular hole (MH) development at the postoperative follow-up. Macular microperimetry confirmed a subclinical reduced macula threshold sensitivity with an anomalous retinal sensitivity analysis map and a stable central foveal fixation site. Conclusions: Even with the successful microstructural disappearance of myopic macular detachment, the last multidisciplinary functional and structural assessments demonstrated different subclinical macular alterations.展开更多
