Methods
All consecutive patients with idiopathic MH who agreed to participate in this study from March 1, 2007 through February 29, 2008 were enrolled and a prospective study was performed. Data collected included patient age and gender, MH stage (Gass classification) and latency (judged by clinical history), cataract grade of mild (nuclear sclerosis 1+) or moderate to advanced (nuclear sclerosis 2+ or 3+), and Snellen best-corrected visual acuity (BCVA) before and after surgery. Postoperative adverse
Results
The study included 16 eyes of 15 patients (7 eyes of 6 females and 9 eyes of 9 male). Age ranged from 54 to 78 years. Preoperative BCVA ranged from 20/400 to 20/30 (mean, 20/200). The possible latency period before surgery ranged from 0 to 9 months. All eyes were phakic. Four eyes had a stage 2 MH (25%), 10 eyes had a stage 3 MH (62.5%), and 2 eyes had a stage 4 MH (12.5%). These are summarized in Table 1. Sizes of MH ranged from 0.15 to 0.4 disc diameter.
Three hours after surgery, 5 eyes were
Discussion
Although the ocular fundus is observable even in a gas-filled eye by conventional TD-OCT, a detailed examination of the macular area is hampered by a strong light reflex. Kasuga and associates reported that 4 (58%) of 7 gas-filled eyes could be observed by TD-OCT on the day after surgery.25 However, findings of the posterior retina depicted by TD-OCT would not necessarily prove MH closure because the macula is not identifiable in a gas-filled eye by several scans of TD-OCT. Especially in the

2019, American Journal of Ophthalmology Case ReportsCitation Excerpt :Vitreoretinal surgeons are divided as to the necessity of prone positioning after macular hole surgery. Anatomical full thickness macular hole closure has been demonstrated to occur in the majority of patients on first postoperative day OCT studies.10 For small macular holes (<400 μm), minimal or no prone positioning may be acceptable to achieve excellent results.11
