Introduction: John Thomas Woolhouse (1666-1733/1734), who practiced in Paris, was part of a family with 5 generations of English oculists. Some historians have derided him as a “charlatan” and have criticized him for adhering to the old notion that a cataract was a membrane anterior to the lens. Methods: We reviewed treatises and digital records related to Woolhouse and his family and the handwritten notes of his 1721 lecture series at the Royal Society of Medicine. Results: We have identified 5 generations of oculists in Woolhouse’s family, by the names of Atwood, Stepkins, Ivy, and Beaumont. Woolhouse taught students from across Europe. He was one of the early proponents in Europe, inspired by Asian medical practices, to perform paracentesis to release aqueous for a new condition called hydrophthalmia. In Woolhouse’s system, some of these cases probably described angle-closure glaucoma. He was the first to attach the name glaucoma to the palpably hard eye in 1707. He may also have been the first to teach that a soft eye was unlikely to recover vision. Credit for these teachings has traditionally gone to one of his students, Johannes Zacharias Platner, in 1745. Some historians have stated that he proposed iridectomy as a theoretical procedure, which was later performed by Cheselden. In fact, Woolhouse described techniques he had performed which today would be called pupilloplasty, synechiolysis, or pupillary membrane lysis. He was also a pioneer in dacryocystectomy for chronic dacryocystitis and in congenital cataract surgery. His writings from 1716 onward repeatedly (and correctly) stressed that most of the patients with visual disorders required depression of the crystalline lens (for what he called glaucoma), as opposed to removal of an anterior membrane (which he called cataract). Conclusions: Woolhouse was a bold ophthalmic innovator and teacher who made major contributions which have lasted to this day. Although he did not admit it, he ultimately adopted much of the evolving understanding of the nature of lens opacities. However, his stubborn refusal to adopt the newer semantics has detracted from a full appreciation of his contributions.

Objective: To evaluate changes in intraocular pressure after congenital cataract surgery in a real-world setting. Methods: This retrospective case series included all children aged 0–2 years undergoing lens extraction due to congenital cataract. Development of an elevated intraocular pressure was divided into three groups: secG, suspG and OHT. Further, risk factors for IOP changes, the therapeutic approach and functional outcome were assessed during follow-up. Results: One hundred and sixty-one eyes of 110 patients aged 0–2 years were included, whereof 29 eyes of 17 children developed secondary glaucoma (secG; 11 eyes/8 patients), glaucoma suspect (suspG; three eyes/three patients) or ocular hypertension (OHT; 15 eyes/10 patients). No difference in surgrical procedure ( p = 0.62) was found, but age at cataract surgery differed significantly ( p = 0.048), with the secG group (1.74 ± 1.01 months) being the youngest (suspG: 3.93 ± 1.80 months; OHT group: 5.91 ± 5.36 months). Secondary surgical intervention was significantly higher in the secG (4.64 ± 3.41) followed by the suspG (2.00 ± 2.65) and OHT groups (0.40 ± 0.74; p < 0.001). Postoperative complications including nystagmus ( p = 0.81), strabismus ( p = 0.98) and amblyopia ( p = 0.73) showed no difference, in contrast to visual axis obscuration which was more common in the secG group ( p = 0.036). Conclusion: Initial lensectomy and anterior vitrectomy procedure together with or without IOL implantation seems to have no influence for the development of IOP changes after pediatric cataract surgery. However, children who developed secondary glaucoma had cataract surgery significantly earlier, within the first 2–3 months of life. Glaucoma surgery was required to achieve final IOP control in most eyes. The development of secondary glaucoma was also associated with a significant increase in surgical re-treatments.

I. In the year 1793, I had the honour of laying before the Royal Society, some observations on the faculty by which the eye accommodates itself to the perception of objects at different distances. The opinion which I then entertained, although it had never been placed exactly in the same light, was neither so new, nor so much forgotten, as was supposed by myself, and by most of those with whom I had any intercourse on the subject. Mr. Hunter, who had long before formed a similar opinion, was still less aware of having been anticipated in it, and was engaged, at the time of his death, in an investigation of the facts relative to it ; an investigation for which, as far as physiology was concerned, he was undoubtedly well qualified. Mr. Home, with the assistance of Mr. Ramsden, whose recent loss this Society cannot but lament, continued the inquiry which Mr. Hunter had begun ; and the results of his experiments appeared very satisfactorily to confute the hypothesis of the muscularity of the crystalline lens. I therefore thought it incumbent on me, to take the earliest opportunity of testifying my persuasion of the justice of Mr. Home’s conclusions, which I accordingly mentioned in a Dissertation published at Gottingen in 1796, and also in an Essay presented last year to this Society. About three months ago, I was induced to resume the subject, by perusing Dr. Porter field’s paper on the internal motions of the eye ; and I have very unexpectedly made some observations, which I think I may venture to appear to be finally conclusive in favour of my former opinion, as far as that opinion attributed to the lens a power of changing its figure. At the same time, I must remark, that every person who has been engaged in experiments of this nature, will be aware of the extreme delicacy and precaution requisite, both in conducting them, and in drawing inferences from them ; and will also readily allow, that no apology is necessary for the fallacies which have misled many others, as well as myself, in the application of those experiments to optical and physiological determinations.
