Recurrent herpes simplex virus ocular infection: epidemiological and clinical features.
The epidemiological and clinical features of recurrent herpes simplex virus ocular infection (RHSV) were studied. Of 108 patients with primary herpes simplex virus ocular infection (PHSV) who were followed up for two to 15 years 35 (32%) suffered one or more recurrent attacks. The recurrence rate was significantly higher in patients under 20 years of age, but there was no significant difference between recurrence rates in males and females. Of 35 patients with RHSV 17 (49%) had one recurrent attack, 14 (40%) had between two and five, and four (11%) had between six and 15 attacks. The mean time interval between PHSV and the first four RHSV attacks was 10 months, and was shorter in subsequent attacks. The duration and severity of RHSV were reduced in successive recurrences. Patients with more severe conjunctivitis and lid lesions during PHSV ocular infection had a higher incidence of recurrent infection. The severity of the corneal signs in PHSV had no influence on the incidence of recurrent infection. Several clinical forms of RHSV were observed. Conjunctivitis associated with lid lesions was observed in 29 (83%) patients. In six (17%) patients the disease presented as an acute follicular conjunctivitis without characteristic lid or corneal lesions. Dendritic ulcer was found in three (9%) patients, and in one of them it was associated with a disciform keratitis. A chronic blepharoconjunctivitis developed in eight (23%) patients. The epidemiological and clinical features of RHSV were compared with those of PHSV.

Corneal astigmatism following cataract extraction.
The changes in corneal curvature in the first six months after cataract extraction were studied by performing sequential keratometry on a group of 57 patients. 8/0 Virgin silk interrupted sutures were used for the closure of corneoscleral incisions, and 10/0 monofilament tied in double running (bootlace) or single running (continuous) fashion was used for corneal wound closure. A high degree of with-the-rule astigmatism was evident in all patients two weeks postoperatively, but thereafter the character of the astigmatism produced by 8/0 virgin silk and 10/0 monofilament closure was quite different: in the 8/0 virgin silk group there was an early and pronounced shift in the axis of astigmatism to against-the-rule, whereas in the 10/0 monofilament group there was little further change in the astigmatism unless the sutures were removed. Wound compression and wound gape as factors responsible for these changes are discussed.

Epidemiological and clinical features of primary herpes simplex virus ocular infection.
The epidemiological and clinical features of primary herpes simplex virus ocular infection in 108 patients were studied. Of these, 69 (64%) were aged 15 or over and only eight (7%) were under the age of 5. Associated upper respiratory tract infection was found in 38 (35%) patients and systemic disorders such as mild malaise, fever, and aching in 34 (31%) patients. Common symptoms were redness, watering, discharge, itching, irritation, and lid swelling, whereas pain, photophobia, lid vesicles and ulcers, and blurred vision were less frequent. The major signs consisted of vesicles and ulcers on the lids, papillary responses which were more severe in the upper lid conjunctiva, follicles which were more common in the lower lid conjunctiva, fine and coarse epithelial punctate keratitis, and subepithelial punctate keratitis. Dendritic ulcers and disciform keratitis were found in 16 (15%) and two (2%) patients respectively. The clinical forms of primary herpes simplex virus ocular infection varied. Moderate or severe disease was observed in 41 (38%) and 16 (15%) patients respectively. In eight (7%) patients the disease presented as an acute follicular conjunctivitis without characteristic lid or corneal lesions. A chronic blepharoconjunctivitis which lasted for months developed in 16 (15%) patients. The epidemiological and clinical features in our patients were compared with features of the disease reported previously.

Rapid culture test for adenovirus isolation.
A rapid culture test has been developed and evaluated for the detection of adenovirus in ocular infections. The test requires only two days' incubation of the inoculated cell monolayers on coverslips in flat bottomed tubes followed by detection of adenovirus inclusions using immunofluorescence staining method. The sensitivity of the rapid test is found to be comparable with that of the conventional tissue culture test which depends on the development of a cytopathic effect requiring 2-21 days' incubation (mean 9 X 4, SD 4 X 9).

Prevalence of acute conjunctivitis caused by chlamydia, adenovirus, and herpes simplex virus in an ophthalmic casualty department.
The causes of acute conjunctivitis in 140 consecutive patients attending an ophthalmic casualty department in London were investigated. Laboratory evidence of infection with Chlamydia trachomatis, adenovirus, or herpes simplex virus was found in 52 (37%) cases. In 70 cases (50%) no evidence of infection with these agents was found. In the remaining 18 cases (13%) laboratory results were inconclusive. The importance of these findings, the role of laboratory investigations in the differential diagnosis of acute conjunctivitis, and their cost-benefit are discussed.
