Glaucoma after penetrating keratoplasty is a frequently observed post-operative complication and is a risk factor for graft failure. Penetrating keratoplasty performed for aphakic and pseudophakic bullous keratopathy and inflammatory conditions are more likely to cause postoperative glaucoma compared with keratoconus and Fuchs' endothelial dystrophy. The intraocular pressure elevation may occur immediately after surgery or in the early to late postoperative period. Read More

Retina 1995 ;15(2):87-90

Retina Department, Duke University Eye Center, Durham, North Carolina 27710, USA.

Background: Silicone oil tamponade is used in treating retinal detachments, but silicone-associated complications remain frequent. Keratopathy and acute pupillary block glaucoma are related to migration of silicone oil into the anterior chamber. Since 1985, many surgeons have created an inferior peripheral iridectomy (PI) at the time of surgery to prevent forward migration of the oil, but the rate of postoperative closure of the PI and the effect on oil position have not been well defined.

Superior peripheral iridectomy has been performed in 40 patients who have undergone silicone oil surgery for retinal detachment and who are aphakic. Only two developed raised intraocular pressure due to pupil block by liquid silicone and in each case the iridectomies seemed to be closed by proliferative membrane rather than the silicone meniscus. This type of iridectomy is particularly suitable in patients requiring intracapsular cataract extraction after previous vitrectomy and silicone oil surgery. Read More

Department of Ophthalmology, Medical College of Wisconsin, Milwaukee.

We injected 25 micrograms of recombinant tissue plasminogen activator into the anterior chamber or the vitreous cavity in seven aphakic patients for pupillary block caused by a complete fibrin pupillary membrane that formed after vitrectomy with fluid-gas exchange. Progressive fibrin deposition resulted in pupillary block by three days after vitrectomy surgery in six patients, and seven days after vitrectomy in one patient. The pupillary block was associated with increased intraocular pressure in six patients. Read More

Br J Ophthalmol 1987 Mar;71(3):197-200

In the aphakic eye, with intact iris diaphragm, silicone oil has frequently caused a pupillary block. In this situation aqueous humour accumulates behind the iris and forces silicone oil through the pupil into the anterior chamber. An iridectomy at the 6 o'clock position can effectively prevent this pupillary block. Read More

Jpn J Ophthalmol 1987 ;31(1):138-46

Among various substances used for intraocular tamponade in the treatment of vitreous opacity and complicated retinal detachment, silicone oil is superior to hyaluronic acid or sulfur hexafluoride. Its low gravity and hydrophobic nature permit good tamponade effect to be obtained and its high transparency allows us to detect remnant vitreous traction in the far periphery and/or retinal tears. Furthermore, preretinal membrane can be peeled off easily after silicone oil removal. Read More

Int Ophthalmol 1985 Sep;8(3):183-6

Pseudophakia by itself does not cause ocular hypertension. Pseudophakic glaucoma should be defined as glaucoma that would not be present in an eye if it were not pseudophakic. Ocular hypertension was noted in 15 (9%) of 166 pseudophakic eyes. Read More

Arch Ophthalmol 1985 Sep;103(9):1350-4

The number of laser iridotomies in 1982 was more than four times the annual rate of surgical iridectomies performed before the laser was in common use at the Bascom Palmer Eye Institute, Miami. No single reason accounts for the increase. Only a minority of the increase is due to a 32% increase in our outpatient volume, a backlog of individuals with borderline indications who had not undergone surgery, or the number of iridotomies performed prophylactically for asymptomatic narrow angles.

Trans Ophthalmol Soc U K 1985 ;104 ( Pt 2):137-41

Pupilloplasty has given positive results in 40 out of 45 cases of aphakic and pseudoaphakic secondary block glaucoma after one or two laser sessions. Since we first applied this method we have arrived at the following conclusions: Pupilloplasty must be repeated whenever the reformation of the anterior chamber achieved with the first laser session does not persist. [In our instances the anterior chamber was successfully reformed at the first session and maintained its depth in 30 of the 40 cases. Read More
